In court, Alva and Alberta Pilliod of Livermore testified that they sprayed Monsanto's herbicide Roundup on their three properties over a period of more than 30 years. Both eventually developed non-Hodgkin's lymphoma, a type of cancer.

Alva was diagnosed in 2011 and Alberta was diagnosed in 2015.

"We've been fighting cancer for nine years now, Al longer than me and it was caused by Roundup. It's changed our lives forever," said Alberta Pilliod.

The couple used Roundup for weed control. One of their attorneys, Michael Miller, said the Pilliods saw Roundup commercials of homeowners spraying the herbicide wearing shorts. As a result, Alberta thought was safe to do the same. "From their ads, we felt that it was incredibly safe to use," she said.

"Now Alberta needs $21,000 worth of medicine a month, or she dies," said Miller.

Their attorney had told the jury that the chances of both of them getting the same type of cancer was one in 20,000.

There are more than 13,000 cases against Monsanto that are expected to go to trial in the United States.

Bayer, which now owns Monsanto, called the verdict disappointing and say they will appeal.

Bayer issued this statement: "We are disappointed with the jury's decision and will appeal the verdict in this case, which conflicts directly with the U.S. Environmental Protection Agency's (EPA) interim registration review decision released just last month, the consensus among leading health regulators worldwide is that glyphosate-based products can be used safely and that glyphosate is not carcinogenic, and the 40 years of extensive scientific research on which their favorable conclusions are based."
